To complement, in the EU, if you have two prices, one on the shelf and one on the box, the cheapest one is the right one. The only goods where prices are printed on the "box" are not in boxes, they are books or clothes.

When items get individual prices, they are usually small sticker prices and effectively only in small shops or discount prices in bigger stores.

It's not entirely that simple - if there's a store branded price on the shelf or a sticker, that takes precedence over any MSRP printed on the product itself by the manufacturer. Otherwise people could just rip off store branded stickers and opt out of the store's markup.

Maybe it's just not become an issue since the MSRP on most product packaging here is in £ or $ as they just reuse the UK or sometimes US packaging so it's clear that price is not aimed at Irish consumers.
